What This Guide Helps With
Printer errors, no paper output, paper jams, or poor print quality caused by paper loading, incorrect media, or mechanical obstruction.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Do not troubleshoot the printer while actively acquiring a diagnostic ECG on a patient.
- If printing is required for care, move to another device first.
- Confirm patient care is not interrupted.
Verify the Reported Issue
- Attempt to print a test ECG or stored record.
- Observe error messages on display.
- Check for no paper feed or partial feed.
- Look for paper stopping mid-print.
- Assess for faded or blank output.
Check Paper Supply and Type
- Open the printer compartment and inspect the paper roll.
- Ensure paper is present and not empty.
- Confirm correct thermal paper type is used.
- Verify paper is not wrinkled, damp, or damaged.
Verify Correct Paper Orientation
- Ensure thermal paper is loaded in the correct direction (thermal side facing the print head).
- Flip the paper roll if unsure and test print.
Inspect for Paper Jam or Debris
- Carefully remove the paper roll and inspect the paper path.
- Look for torn paper pieces.
- Remove any debris or obstruction.
- Ensure rollers move freely.
Reload Paper Properly
- Reinstall the paper roll evenly in the holder.
- Feed paper straight through the exit slot.
- Close the printer door securely.
Check Printer Door and Latch
- Ensure the printer cover is fully closed and latched.
- Verify no latch or cover errors are present.
Perform a Test Print
- Run a test ECG or internal print function.
- Observe smooth paper feed.
- Confirm consistent print quality.
- Ensure no error messages are present.
Power Cycle the Device
- Turn the unit off.
- Wait 10–15 seconds.
- Power the device back on.
- Verify printer resets and resumes normal function.
If the Problem Persists
If paper is correctly loaded, the path is clear, and errors continue, the issue is likely internal (print head, motor, or sensor failure).
Remove the device from service, label it Out of Service, and send for repair or bench evaluation.
Clinical Use Tip
Do not troubleshoot on an active patient. Always move the patient to a backup device first to maintain continuous care and ensure therapy is not interrupted.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"EKG machine not printing and displaying paper jam error during use."
Cause
What was observed during troubleshooting.
Example:
"Paper roll installed incorrectly and partial paper obstruction found in feed path."
Resolution
What action was taken.
Example:
"Cleared jam, reloaded paper correctly, and verified proper print function."
Helpful Details to Include (If Known)
- Alarm or error message behavior
- Accessories swapped (paper roll replaced)
- Power behavior during printing
- Environmental factors (humidity affecting paper)
- Indicator lights or display messages
- Final device status (returned to service or sent for repair)
Final Thought
Thermal printer issues are most often caused by simple external factors like paper loading or debris. A structured, step-by-step approach prevents unnecessary escalation while ensuring reliable ECG documentation. Always prioritize patient care and accurate records, and escalate when internal faults are suspected.
That is successful troubleshooting.
